TCA Chemical Peel

Friday, May 20th 2011. | Skin Care

Trichloroacetic (TCA) has become the gold normal of chemical peeling agents. it’s been well studied, it’s versatile in its ability to form peels of various depths, it’s stable, cheap, and nontoxic.

TCA may be a chemical cauterant, that coagulates proteins within the skin. this can be presumably the idea for the formation of the white frost seen when TCA is applied to the skin. The deeper the peel performed with TCA, the faster and additional intensely white the frost. The intensity of the frost and its associated skin turgor are used to guage the depth of the peel. the amount of frost created by superficial and medium depth peels are often classified into four teams

Level 0 – No frost: The skin may look and feel a little slick and shiny, but there is no frost and minimal or no erythema. This is a very superficial peel that, at most, removes the stratum corneum.

Level 1 – Irregular light frost: In addition to appearing shiny, the skin shows some erythema and scattered areas of wispy white frost. This is a superficial epidermal peel that creates 2 to 4 days of light flaking.

Level 2 – White frost with pink showing through: The skni has a uniform white color but there is a strong pink background. This is a full thickness epidermal peel that takes about 5 days to heal.

Level 3 – Solid white frost: The skin has a solid, intense white frost with no pink background showing through. This is a peel that extends into the papillary dermis and takes 5 to 7 days to heal.

These levels of frost are guidelines, they vary a bit from patient to patient.

You should expect certain things when healing from a TCA peel:

The skin will look and feel tight, as if it were covered with a sheet of plastic.
Any area of epidermal hyperpigmentation will darken considerably as part of its reaction to the peel.
Varying degrees of swelling can occur. It is rare to see such edema with superficial peels, but some edema is common with papillary dermal peels. The edema usually peaks 48 hours after the peel.
The first areas to begin peeling will be the areas with the most muscle movement.
The forehead and hairline are usually the last areas to peel.
